The Deep Mind vs Stockfish result is amazing especially given how the new AI works. I've always felt that the opening/endgame tables used in modern chess engines were kind of cheating - why couldn't Kasparov take his notes into the Deep Blue game? To see a AI learn and dominate the game from scratch is incredible.

The Pro Chess League was interesting but I didn't watch it often as there was no easy way to just watch one team's games so I couldn't easily track how the Irish team were doing. Hopefully next year each time will have their own page on the site showing just their games.
